PAPER-FILE.

To all whom 'it may concern:

Be it known that I, CHARLES E. GIBBS, of Maiden, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Paper-Files, &c., of which the following is aspecification.

This invention relates chiefly to a file for holding sheets of paper,and comprising a flat board or support of wood or other compressiblematerial having projecting pointed studs on which sheets of paper may beimpaled, and a hinged spring-pressed clamping plate, one edge of whichis pressed yieldingly toward the support and is provided with orificesadapted to receive said studs, the clamping plate being provided withguards which cover the pointed ends of the studs and prevent them frominflicting injury.

The invention has for its object,'first, to provide an improvedconstruction whereby the studs are secured to the wooden back or supportand, secondly, to provide an improved construction of the clamping plateand the stud guards.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings forming a part of thisspecification,-Figure 1 represents a side view of a paper file embodyingmy invention, a part of the support being broken away. Fig. 2 representsan edge view of the parts shown in Fig. 1. Fig. 3 represents a sectionon line 33, Fig. 1. Fig. 4 represents a side view of one of the impalingstuds. Fig. 5 represents a sectional view of one of the washershereinafter referred to. Fig. 6 represents in section a portion of theclamping plate without the stud guard. Fig. 7 represents the side viewof one of the stud guards removed from the clamping plate.

Similar reference characters indicate the same or similar parts in allthe views.

In the drawings, 12 represents a flat support of compressible materialsuch as wood, the support being preferably a suitably fin ished boardadapted to support sheets of paper and the securing devices hereinafterdescribed. The board is provided with one or more pointed studs whichproject from the outer side of the board at right angles therewithsothat sheets of paper maybe im- Specification of Letters Patent.

paled upon the studs. Each stud is composed of a pointed outer portion13, a rivetshaped inner portion 1 1, and a peripheral ridge orenlargement 15 between the portions 13 and 14, said enlargement beingrelatively near the outer end of the portion 141. The stud is preferablymade of a single length of wire subjected to suitable pressure whichforms the ridge 15 integral with the body of the stud. In securing thestud to the support 12, I form an orifice through the support, and placeon opposite sides of the support two washers 16 and 17 which are, bysuitable pressure, caused to indent the sides of the support so that theouter sides of the washers are substantially flush with the sides of thesupport, the orifices of the washers coinciding with the orifice throughthe support. The washer 16 is provided with a socket 18 formed toreceive the ridge 15, the form of the socket being such that when theridge is inserted in it, the outer side of the ridge is substantiallyflush with the outer side of the washer 16 and support 12, as shown inFig. 3. The rivet portion 1 1, is of such length that it is adapted topass through the support and the two washers, and project from the outersurface of the washer 17 sufliciently to permit its end portion to beupsetand form a head 19 which engages the washer 17. The stud is thusrigidly connected to the support, the entire body portion of the studwhich projects from the outer side of the support being of uniformdiameter and a *ailable for the support of paper sheets.

20 represents a clamping plate having cars 21 which are pivoted at 22 tocars formed on a plate 24 fixed to the support 12. A spring 26 supportedby the pivot rod 22 bears on the clamping plate at one side of thehinged connection, and holds the edge of the clamping plate at theopposite side of said connection yieldii'igly against the support 12.The plate 20 is therefore adapted to clamp sheets of paper against thefront side of the support. The clamping plate is provided with orificeswhich coincide with the studs 13, the latter projecting through the saidorifices when the device is 1 in use.

It will be observed that when the clamp ing edge of the plate 20 ispressed inwardly against the support, as shown in Figs. 2 and 3, theplate is inclined relatively to the studs 13, the latter being obliquelyarranged relatively to the plate.

30 represents a tubular guard which is adapted to be inserted andsecured in the orifices 25, the guard having an open inner end and aclosed outer end, and its form being such that it is adapted to coverthe point and the major portion of the stud 13 as indicated in Fig. 3,thus preventing the pointed end of the stud from inflicting injury. Theguard-receiving orifice 25 is obliquely ar ranged relatively to thesides of the plate 20 so that when the inner end'of the guard is seatedon the wall of the orifice, the guard stands obliquely to the sides ofthe plate. The guard is preferably made from a single piece or blank ofsheet metal, the blank being originally flat and converted into the formshown, by a series of operations wellknown to metal workers. The innerend of the guard, which is formed to closely fit the orifice 25, may besecured in said orifice in any suitable way, preferably by means of aninternal screw-thread 27,

Fig. 6, formed in the orifice 25, and an external screw-thread 28, Fig.7, formed on the inner end portion of the guard. The guard is thereforeadapted to be screwed into the plate, and may be additionally secured bysolder, if desired.

I do not limit myself to the improved connection between the support 12and the stud 13 in a paper file, it being obvious that a stud adapted inthis way to a compressible support may be used for other purposes.

' Iclaim:

1. A device of the character stated comprising a support-of,compressible material, such as wood, a'jstud having a rivet-shaped innerportion extending through the support, and a peripheral ridge near theouter end ofthe rivet portion, washers pressed into the opposite sidesof the supporflwith their outer faces flush with the corresponding facesof said support, one of said washers having a socketforming a seat forsaid ridge, whereby the outer side of the latter is flush with the faceof said support, the other washer being engaged with the upset end ofthe rivet portion.

2. A device of the character stated com prising a support having apointed impaling stud and a spring pressed clamping plate, hinged tosaid support and provided with an orifice arranged to receive said stud,said orifice bein screw threaded and obliquely arranged re atively tothe sides of the plate, and a tubular guard having a closed outer endformed to cover the pointed end of the stud, said guard being formedindependently of the plate and eXteriorly threaded to engage the threadsin said orifice whereby said guards are supported in an inclinedposition relatively to the sides of the plate.

In testimony whereof I have afiixed my signature, in presence of twowitnesses.
